Notice of General Meeting

Jubilee, the integrated copper producer and resource developer in Zambia, announces that the Company is seeking to renew the standard authority to grant Directors authority to allot and issue shares or grant rights to subscribe for or convert any securities into shares up to a maximum of 7.5% of the entire issued ordinary share capital of the Company. The Company further wishes to dis-apply pre-emption rights to a maximum of 7.5% of the entire issued ordinary share capital of the Company.

The authorities sought are intended to provide the Company with the flexibility to support Jubilee's copper exploration and mining strategy in Zambia, including the accelerated development of the broader Molefe Mine region.

In line with this strategy, Jubilee has secured a US$1.5 million unsecured convertible loan note investment specifically designated for the accelerated development of the greater Molefe region (refer to the announcement dated 28 May 2026). The investor holds a successful track record in the development of various copper projects and formed part of the team behind the development of Mantos Copper and its subsequent merger with Capstone Copper (Investor). This initial investment reflects the Investor's keen interest in supporting Jubilee's copper exploration and mining strategy in Zambia, including the development of the greater Molefe region, beyond the current mining area.

The Company believes the combination of exploration, mining and access to nearby refining capacity through the Sable Refinery offers a unique opportunity to accelerate copper production while simultaneously advancing detailed resource drilling and regional exploration activities.

Notice is hereby given of the General Meeting (GM) of the Company to be held at 11.00 a.m. (UK time), 12.00 p.m. (SA time) on Monday, 15 June 2026 at Fieldfisher LLP, Riverbank House, 2 Swan Lane, London EC4R 3TT to consider and vote on the resolutions.

The circular containing the notice of General Meeting (Notice of GM) will be published and posted to shareholders on Friday, 29 May 2026 (Circular). A copy of the Circular containing the notice of GM is also available on the Company's website at https://jubileemetalsgroup.com/circulars/.
